Title: Semiconductor switch unit
Inventor: UCHIDA RIYOUHEI
IPC: H02M1/08
Filed: 1977-12-29
Abstract: PURPOSE: To perform stable commutation by providing a transformer which supplies a base current answering to the collector current of a commutating transistor and that which supplies a reverse bias to a main thyrister.  
     CONSTITUTION: When a current is flowing to load Z with thyristor CR ignited, turning ON auxiliary transistor TrQC applies the voltage of control power supply V c  to the series circuit of windings N 12  and N 22  of transformers T 1  and T 2 , the induced voltage of winding N 21  of T 2  supplies base current (iB) of commutating TrQM to turn On TrQM, and the sum of induced voltages of windings N 11  and N 21  of T 1  and T 2  supplies a reverse voltage to thyristor CR. As a result thyristor current (iCR) is commutated as collector current (i c ) toward TrQM and afterward, TrQM commutates all current (iCR) while maintaining itself in the saturation state. In this case, stable commutation can be performed by automatically decreasing or increasing current (iB) via induced current (i 2 ) of winding N 12  corresponding to current (i c ) and by decreasing a control current with a winding ratio between transformers T 1  and T 2  made large.

Title: Stop controller for unmanned vehicle
Inventor: KOKUNE HAJIME
IPC: G05D1/02
Filed: 1987-06-26
Abstract: PURPOSE:To stop an unmanned vehicle at a prescribed position regardless of the presence or absence of a cargo by using a cargo detecting means and a stop control mean which changes the driving speed of the vehicle for deceleration in accordance with the presence or absence of cargos and controls a driving motor. CONSTITUTION:When a panel detection sensor 5b detects an indicated panel P1b while an unmanned vehicle 1 containing no load is running toward a delivery station S2, a CPU 12 is set under a stop mode and judges the presence or absence of cargoes from the detection signal of a limit switch 9. When the absence of cargos is confirmed, the time Ta and the velocity V set right before deceleration are read out of ROM 13 to obtain the momentary speed command value Vt(=-V.T/Ta). This value Vt is successively outputted to the motor driving circuits 15 and 16 based on the counted time of a timer 12a. In case the vehicle 1 carries cargoes, the command value Vt(=-V.T/Tb) of a large deceleration degree is obtained in the same way and outputted to both circuits 15 and 16. Thus the vehicle 1 stops accurately at a stop position St2 in any case.

Title: Controlling method for multipled current type inverter
Inventor: MINAMOTO MASAHIRO
IPC: H02M7/48
Filed: 1979-12-12
Abstract: PURPOSE:To reduce a harmonic content in a wide range by controlling a unit inverter so that the both-side part of a rectangular wave whose width is larger by a prescribed angle than the width of 120 deg. is cut into a pulse form within the range of low-speed operation of an AC motor. CONSTITUTION:A plurality of unit current type inverters INV1 and INV2 are connected in parallel on the output side, the control pulse phases of the corresponding thyristors of each inverter are slided from each other, and thus resultant output current of multiple staged waveform is supplied to the motor M. Moreover, in the range of low-speed operation, each inverter is controlled so that both-side part of the rectangular wave whose width is larger by a pescribed angle than the width of 180 deg. is cut into a pulse form, while the prescribed angle of the sections cut into the pulde form is selected so that these sections are not overlapped. Accordingly, in the range of high-speed operation, by discontinuing the pulse-form cut automatically, the harmonic content is reduced in the wide range of frequencies and thereby the pulsation of torque can be reduced.
